TK65018

DESCRIPTION

The TK65018 is a monolithic switched capacitor converter

with regulation. With just two capacitors, the TK65018 can

create a negative voltage supply with regulation.

With no external timing elements, the converter will self-

oscillate at 166 kHz, nominal.

Quiescent current is typically 50

µA. Standby current is

guaranteed less than 2

µA over the full operating

temperature and input voltage ranges.

The TK65018 is available in miniature SOT-23L-6 surface

mount package. Customized levels of output voltages are

available. The TK65018 is available with the following

output voltages: -5.0 V, -4.1 V, -3.5 V, -3.0 V, -2.1 V, -1.5,

-0.5 V.
